NAD Electronics has announced that its C 658 BluOS streaming digital-to-analog converter (DAC) preamplifier will soon be equipped with Dirac Research’s Dirac Live room correction software, via a mid-June software update available to all owners of the component.
Dirac Live is designed to measure the energy and time it takes for both direct and reflected sound waves to travel from the speakers to a user-defined listening area, from which it calculates precision filters to counteract a room’s anomalies without changing the inherent sound characteristics of the audio system.
The C 658 includes a microphone so users can calibrate their listening environment using Dirac’s proprietary app, available for desktop, iOS, and Android devices. Up to five listening profiles can be stored. Tone and room correction controls can be accessed with the Dirac app, while the BluOS Controller app contains basic controls, allowing a user to select filters, adjust subwoofer crossover settings, or disable Dirac.
Dirac Live will make these compensations up to 500Hz. Users interested in room correction across the full frequency range can easily upgrade to Dirac Live Full, says NAD.
“Speaker placement is hard to get right,” explained Cas Oostvogel, NAD’s product manager. “You are limited by practicalities like leaving doorways clear, placement of other furniture, and location of electrical outlets. Dirac Live essentially does the heavy lifting to make your music sound as if your speakers were ideally placed.”
